'''Elostirion''' was the tallest and westernmost of the three [[White Towers]] that stood on the [[Tower Hills]]<ref>{{FR|Hobbits}}</ref> and that had been built by [[Gil-galad]] for [[Elendil]]. It held one of the [[palantíri|palantír]] of [[Arnor]] which did not communicate with the rest but looked only westward across the Sundering Seas to [[Tol Eressëa]]. This, the last palantír of [[Arnor]], was carried back across the sea with the departure of the [[Ring-bearer|ring-bearers]] early in the [[Fourth Age]].<ref>{{UT|Palantiri}}</ref>
